Within the six ROIs showing interference-related probe activity during the LE condition, there were no subregions that showed significant gF effects or gF x interference expectancy interactions.
Similarly, the three ROIs that showed recency effects for positive probes during the LE condition failed to show gF effects or interactions between gF and interference expectancy.
Within the LE condition, 10% of trials were recent negatives, 40% were recent positives, 40% were novel negatives, and 10% were novel positives.
The above analysis procedure was conducted to detect regions that showed greater activity during the HE condition than the LE condition.
In the current study, several anatomical regions showed effects consistent with both proactive control during the HE condition and reactive control during the LE condition.
In the current study, there was evidence that pre-SMA showed reactive control during the LE condition and proactive control during the HE condition.
Conversely, in the LE condition, the primary dependence on reactive control should be reflected as increased probe-related activation, especially on recent negative trials, replicating prior results [15].
In the low expectancy (LE) condition, only 20% of recent probes were recent negatives, whereas in the high expectancy (HE) condition, 80% of recent probes were recent negatives.
